Hi,

I pulled the flywheel off the kerbside pick up one yesterday. The flywheel had the toothed ring around the outside which I guess must be for an electric start, but this machine was normal start. I have never seen a complete electric model. Where do they mount the starter? Charge the battery from the magneto I suppose. The piston looks very similar to the OP's pictures. Looks like this was just a collection of bits & pieces that someone put together hoping it would go. Ah well you can not expect much for nothing.

Still got a good starter, a flywheel and the carby is all there. Muffler fell apart on removal.

All the best
Jeff
